A U TO M AT I C F I R E S P R I N K L E RP R OT E C T I O NResidential fire sprinkler system installations areincreasing every day thanks to growing buyerdemand, lower costs, and simpler installation.Offering sprinkler systems in the homes youbuild puts your company on the cutting edge andgives your homes a distinct security advantagethat homebuyers want and need.Every home fire starts small. If it goes unchecked,a home fire grows and spreads quickly, reachingextreme heat and spreading highly toxic smoke.No one can survive a fire that reaches this level.According to the National Institute of Standardsand Technology (NIST), a home fire can reachdeadly proportions in only three minutes or less.A home fire sprinkler system works automaticallyat the earliest stage of fire growth, controllingthe flames before they can build deadly heat andsmoke. This gives families the time they need tosafely escape – even very young children andolder adults who may not be able to get out ontheir own – and limits the extent of damage to asingle area of the home.“Fire sprinklers give me peace of mind,especially at night when my childrenare sleeping.” – SANDRA KUHNS, HOMEOWNERIn a typical fire, 7-10 minutes or longer will havepassed from the time the fire starts, is discoveredand reported to the time the fire trucks roll up tothe scene. In homes without fire sprinklers, thatmeans the fire will have continued to burn –growing and spreading. Even if the residentswere fortunate enough to escape unharmed,their home would likely be a total loss.When you build a home with an automatic firesprinkler system, it’s built for life.

You makecustomer confidence a top priority.That’s good business and it pays off.Today, customer confidence is affected bymore than just comfort, convenience andquality. Savvy buyers also want to knowtheir loved ones, pets and belongings aresafe within their new homes. Wisebuilders make sure they offer thosebuyers what it takes to gain their trustand earn their business.That’s one of the reasons why morebuilders than ever are offering automaticfire sprinkler systems in the new homesthey build.Graphic Source: Tyco Fire Products

TA K E A L O O K AT A H O M E SY ST E MA typical residential fire sprinkler systemoperates off the household water main and usespiping that is installed behind walls and ceilingsin finished areas.Attached to the piping atintervals are the individualsprinklers. Concealedsprinklers are often usedin finished areas. Anunfinished basement mayhave exposed piping andpendent sprinklers insteadof concealed sprinklers.Each sprinkler can protect a minimum area of12 x 12 feet. Extended coverage sprinklers areavailable that protect even larger areas.Sprinklers activate independently – unlike hardwired and interconnected smoke alarms. If thereis a fire, only the sprinkler closest to the flameswill operate. A recent study showed that in about90% of home fires, only one sprinkler wasnecessary to control the fire.Custom builder? No problem! A wide variety ofsprinkler designs makes it possible to installsprinklers in any type of new home – even homeswith specialty layouts, high or sloped ceilings andother distinctive configurations.Sprinkler systems are designed specifically for thehomes where they’ll be installed, by experts whohave experience creating systems that are highlyeffective and also efficient.Home fire sprinklers can be seamlesslyincorporated into any interior design, withoutsacrificing comfort or style. That adds to yourcredibility as a builder, and that’s important toyour bottom line.

N F PA 1 3 D – TH E N ATI O N A L STA N DA R DThe national installation standard for homefire sprinkler systems is NFPA 13D, Standard forInstallation of Sprinkler Systems in One- andTwo-Family Dwellings and Manufactured Homes.Compliance with NFPA 13D is intended to preventinjury, life loss and property damage. The standardrequires at least 10 minutes of sprinkler water onthe fire in its initial stage of development. Thatcontrols the fire early, giving residents the time toescape safely and the fire department time torespond. A typical home fire will be controlled andmay even be extinguished by the time the firedepartment arrives.In a survey of more than 1,000 adults,47% said they would definitely considerinstalling a home fire sprinkler systemif they were building a new home.– NFPA 2004 FIRE SAFETY SURVEY.NFPA 13D requires sprinklers to be installed onlyin living areas. The standard does not requiresprinklers in smaller bathrooms or closets,pantries, garages or carports, attached openstructures, attics, and other concealed nonliving spaces.The local building authority where you build mayhave requirements that exceed NFPA 13D, soyou’ll want to determine local requirementsahead of time.Two common types of fire sprinkler systems areacceptable under NFPA 13D – stand-alone (orindependent) systems, and multi-purposecombined (or network) systems.

F I R E D O E S N ’ T D I S C R I M I N AT EThe homes you build are safe from avariety of dangers. But are they safe fromfire? According to the National FireProtection Association (nfpa), fire is morecommon and often more deadly thanhurricanes, tornados and other disasters.

EDABCT Y P I C A L S P R I N K L E R WAT E R S U P P LYHere’s what you’ll have with a typical standalone system. The water supply for the sprinklerscomes from the household water main. There willbe a “T” connection between the main and thewater meter, feeding the sprinklers. This is calledthe “riser.”The riser is really the brains of the system. Itincludes the pressure gauge, a flow switch and abackflow valve (where required) and the test anddrain assembly. NFPA 13D doesn’t require a flowalarm, but your local codes might.The flow switch monitors any water flowthrough the system and is wired to an inside bell.The flow switch can also be wired to an outsideIn homes that aren’t on a municipalwater supply – for example, a home witha well – or where the water pressure isvery low, a tank and pump are used toensure water pressure. A pump and a 300gallon tank provide the 10 minutes ofwater supply required by NFPA 13D.

The switch canalso be connected to amonitored security system.Backflow preventiondevices are required insome areas. They areinstalled to isolate thewater used for sprinklersfrom the water used fordomestic purposes, to prevent any crosscontamination of potable water. Backflowprevention devices and water meters reduce theavailable pressure for the sprinkler system,however, so when they are used it is necessary touse larger water taps and meters of at least oneinch or more. Your sprinkler contractor will ensureyou have the information you need to know abouttaps and meters before you install the system.

L O W E R CO ST, E A S I E R I N STA L L AT I O N SOne of the reasons that sprinkler systems havebecome so cost-effective for homes is that nowplastic pipe can be used. CPVC (chloro-polyvinylchloride) is the light-weight material used forplastic piping. Special glue secures the CPVC pipeconnections, reducing the problems of sweatingcopper joints or threading steel pipe.Either plastic or copper pipe is typically used inunfinished basements. CPVC pipes are fed off ariser passing through the interior wall space tothe upper floors.NFPA 13D does not require sprinklers in unfinishedattics. In regions where freezing is a concern, pipesare installed in the walls instead. In finished atticsand in warm regions, pipe can be run up into theattic and ceiling sprinklers can be used.SPRINKLERSBased on the unique floor plan of the homeyou’re building, the sprinkler designer determinesthe piping design and the appropriate number,type and layout of sprinklers along the piping.Since sprinklers cover a minimum 12 x 12 footarea, while extended sprinklers can cover up to a20 x 20 foot area, in many rooms you’ll have asingle sprinkler. Larger areas will be protected byadditional sprinklers or special extendedcoverage sprinklers. For example, in a typicalunfinished basement, three pendent sprinklerswould be used to protect the far sides of the areaand near the center stairway.The NFPA 13D standard permits positioningsprinklers in basements to anticipate future ceilingfinishing – a flexibility selling point for your buyersSidewall SprinklerConcealed SprinklerPendent Sprinkler

who are thinking ahead. If you finish the basement,concealed sprinklers can be used immediately.When you get up into the finished areas of thehome, concealed sprinklers can be used in theceilings. Wall-mounted, semi-recessed sprinklersare used when you want to avoid placing pipes inan unfinished attic.S p r i n k l e r s p r o v i d e t h e u lt i m at efire protectionIf you don’t build with sprinkler systems,your homes are only partly protected fromfire. Local building and fire codes most likelyrequire you to install hard-wired smokealarms, and these provide a crucialcomponent of a home fire safety system –early warning.But the protection afforded by smoke alarmsrequires quick and proper action by residentsto save lives – the alarms signal a fire while itis still small, giving the residents extra timeto follow their escape plan and get out.Sprinkler systems provide automaticprotection – they put water on the flamesimmediately, controlling or extinguishingthe fire in time to save lives.The safest home is a home with smoke alarmsand a fire sprinkler system.Nationally, eight out of 10 fire deaths takeplace in homes very much like the ones youbuild – colonial and ranch, large and small,fancy and plain. Fire can strike anyone, at anytime. If given the opportunity, your customerswould choose to live in a home protected byfire sprinklers.

FIND A CONTRACTOR: VISITHomeFireSprinkler.org“We work very closely to coordinatewith the other contractors – theplumbing and HVAC contractors and theelectrician. It’s important to maintaingood communication with the builder,because we have to rough our system inthe walls before the dry wall. “- COLLEEN McNALLY, U.S. FIRE PROTECTION

WORKI NG AS A TEA MThe most important decisionyou’ll make is choosing yoursprinkler contractor. You wantsomeone who is qualified asa specialist in sprinklerinstallation. The NFPA 13Dstandard says only people“knowledgeable and trained”should install sprinklersystems.Choose a contractor who strictly adheres toNFPA 13D and complies with any additionalrequirements of local codes. You want someonewith experience and someone who knows his orher way around town hall.Once you have your sprinkler partner, you’ll meetwith the fire officials and go from there. A goodsprinkler contractor will help navigate any codeconcerns, water usage issues, permits, etc.,helping you stay on schedule and on budget.The sprinkler contractor’s first step will beto prepare shop drawings and hydrauliccalculations, to make sure the systemperformance will comply with minimum coderequirements. This is usually submitted forapproval during the permit process.Fire sprinkler systems can be roughed in anytimeafter the plumbing and HVAC installation, andtrimmed at the same time other contractorsare working.“ fires today seem to burn faster andkill quicker, because the contents ofmodern homes (such as furnishings)can burn faster and more intensely.” –RICHARD BUKOWSKI, NATIONAL INSTITUTE OF STANDARDSAND TECHNOLOGY RESEARCHER

P R OT E C T I N G YO U R B OT TO M L I N EOn top of increased safety for your customersand value added to the homes you build, you maybe able to benefit from cost-saving incentives aswell. Many municipalities offer what’s known as“trade ups” for builders and designers who sellsprinklered homes.The options vary widely, which is one of thereasons you will want to meet with fire and codeofficials early on. Examples of typical trade upsfor a sprinklered development or sub-divisioninclude street widthreduction, additional units,and increased hydrantspacing. Bundled together,trade ups can net a buildersignificant savings.Another option toexplore is building codealternatives, which mightinclude a reduction in fire-rated portioningrequirements between the living spaces of thehome and other spaces, such as an attachedgarage. Sprinkler trade ups and code alternativescan substantially offset the cost of sprinklerinstallation.E A SY H O M E M A I N T E N A N C ESprinkler systems require very little maintenance. Infact, the sprinklers themselves require none at all.The flow switch and water flow alarms need tobe tested at least once a year to be sure they areoperating. And occasionally, the system should bevisually inspected to check for any obstructionsand to ensure all valves are open. These simplemaintenance steps can be handled by either thehomeowner or sprinkler contractor. That’s it.L I K E H AV I N G A F I R E F I G HTE R O ND U T Y 2 4 H O U R S A DAY.Every year, thousands of lives are lost to homefires because the residents couldn’t or didn’t

Fire sprinkler technology has beenaround for well over a century, with astrong and successful track record ofboth life safety and property protection.Widely used in hotels, hospitals, high-risebuildings and commercial constructionfor decades, automatic fire sprinklersare rapidly gaining popularity in homesas well.Because they provide such a high level ofproperty protection, some municipalitiesrequire sprinkler systems to be installedin new construction of one- and twofamily homes.“If you can put fire sprinklers in homesto protect homeowners and work withthe local jurisdiction to reduce coststhrough trade ups, it’s clearly a winwin situation for everybody involved.”ROB CAMPBELL, ARBOR CUSTOM HOMESrespond quickly enoughwhen fire broke out. Whenyou build with sprinklers,your customers will beprotected from that kindof needless tragedybecause they’ll be living ina home with automaticfire protection.Home fire sprinklers are the future of fire safety.Sprinklers save lives and protect property. That’svalue added for your customers.
